Subject: [PATCH rcu v2 02/10] rcutorture: Set CONFIG_BOOTPARAM_HOTPLUG_CPU0 to offline CPU 0
Date: Wed, 22 Mar 2023 21:39:27 -0700	[thread overview]
Message-ID: <20230323043935.1221184-3-boqun.feng@gmail.com> (raw)
In-Reply-To: <20230323043935.1221184-1-boqun.feng@gmail.com>

From: "Paul E. McKenney" <paulmck@kernel.org>

There is now a BOOTPARAM_HOTPLUG_CPU0 Kconfig option that allows CPU 0
to be offlined on x86 systems.  This commit therefore sets this option in
the TREE01 rcutorture scenario in order to regularly test this capability.
